The Opera House owes Bob a tremendous debt for his expert stewardship through many important developments. His passion, professionalism and perseverance were crucial to the significant achievements of the Vehicle Access and Pedestrian Safety project. He presided over the Building Committee as the Opera House was inscribed on the State (2003), National (2005) and UNESCO World Heritage (2007) lists, which recognise the unique qualities of Jørn Utzon’s extraordinary landmark and help to ensure it will be appropriately protected and conserved. Bob also played a key role in establishing the Eminent Architects Panel and in the publication of the Conservation Management Plan (3rd Edition), the Sydney Opera House Renewal Framework and Utzon’s Gold Book, as well as countless building improvement and major maintenance projects. Bob was a true gentleman, whose wise guidance was always coupled with kindness and respect. He helped to ensure the Opera House is well positioned to remain one of the world’s greatest buildings and performing arts centres for generations to come. His friendship, leadership and generosity are greatly missed. 4 5 The Sydney Opera House’s Vehicle Access and The Vehicle Access and Pedestrian Safety project Pedestrian Safety project was an extraordinarily relied on the vision, dedication and collaborative challenging and complex undertaking.

Kristina Keneally announcement, 6 June, 2010 10 11 Past – 2010 Before the underground loading dock was built, visitors arriving at the Opera House on foot shared the Forecourt with more than 1,000 heavy-vehicle movements a week. This not only diminished the experience for tens of thousands of visitors every day, but also posed a safety risk. In 2010, the NSW Government announced its support for the Opera House to embark on a complex engineering project, known as the Vehicle Access and Pedestrian Safety project. Conceived in 2001 as part of the Opera House’s Strategic Building Plan, it was the largest construction project undertaken since the Opera House opened in 1973. The aim was to divert vehicle traffic to a new tunnel and underground loading dock, turning the Forecourt into a pedestrian plaza for the general public – as Opera House architect Jørn Utzon originally intended. This book tells a visual story of the complex design, engineering and logistical challenges in constructing an underground loading dock beneath a UNESCO World Heritage-listed masterpiece that is also one of the busiest performing arts centres in the world. 10 11 2009 Vehicle movement on the Forecourt and Broadwalks before the project. 12 13 VEHICLE MOVEMENT ROADWAY LEVELLING UNDERGROUND LOADING DOCK BENNELONG ust ust DRAIN DIVERSION ENTRY RAMP VEHICLE MOVEMENT DIVERSION EXISTING (PRE-2010) PROPOSED Before the project, vehicles and pedestrians shared the forecourt.
